| Abstract(in English) | In satellite positioning, receiving multipath signals and non-line-of-sight (NLOS) signals increases the positioning error. In order to realize high-accuracy positioning in urban areas, it is necessary to detect satellites including multipath errors. To solve this problem, we propose a method to evaluate the signal state received from each satellite by testing the consistency between the antenna attitude and the phase difference between multiple antennas. Since this method uses only carrier phase without code pseudorange, it is possible to detect minute errors that affect high-accuracy positioning. In this paper, we evaluate the residual between observed phase differences and estimated ones using calculated antenna attitude. |
